Adding JButtons at Set Intervals

Well I actually have two questions.

First:

This is simple and I am missing a simple answer. First is how can I
change the background colour on a JButton? For example to colour is
currently gray but I want to change it to gree.

Second:

I am trying to figure out a way to add a JButton to a JPanel at a set
interval. Say every 10 seconds. How would I go about doing that?

Regards,
Jeff

Oops... I answered Jeff's crosspost about the second question in another
group with a fairly complete example (hey, I just felt like it!) but
didn't think to use javax.swing.Timer . Could have saved a few lines of
code.

Thanks for reminding me of it!
